Our Happy Customers

  • review rating 5  Good company and products. The team of Comfort Windows & Doors installed three doors for us that are very good quality, they cam back for service when we needed, no issues. I recommended them already to my neighbors

    thumb Luz Reed

    review rating 5  Highly recommend Julian and his professional installers. All of the work was done quickly and they left the areas clean. The new front doors look beautiful from the inside and out!

    thumb Robbie Shelson

    review rating 5  Comfort Windows is amazing. First I did my front door with them and they did a fantastic job so I called them back to do all my windows. I love supporting Canadian companies as well so it was a win-win situation for me. The installers were very professional and knowledgeable, they took their time on my project to make sure it was done to my satisfaction. I also want to thank Julian who went out of his way to make my experience a memorable one. Julian understood my situation and worked with me through everything. He solved problems that arose at the very last minute with such grace. Julian is the best salesman that I have worked. I would highly recommend Comfort Windows and Doors to anyone who is in the market for new windows and doors

  • review rating 5  Julian and the crew did a job for me to replace my side lites and door from the front of the house during the hottest day of the year. Amazing work, could not have been happier with it. Everything was so professional and reasonably priced. And best part was it was done in 1 day and everything was kept clean and respectful for the house. Would recommend them to anyone and will use again in the future! Thanks Julian! Great stuff...

    thumb Amir K

    review rating 5  We had our Windows & entry door replaced by Comfort Windows, and they are beautiful. Our house looks so different and much more modern now. Julian's crew was professional, with excellent work ethic. One of our neighbours is already planning on using Comfort Windows to change their windows/doors as well

    thumb Shoshana K.

    review rating 5  Comfort Windows & Doors did a fantastic job replacing our outer doors. They were a pleasure to deal with and despite it being absolutely freezing the day of the install, the guys could not have been more pleasant and efficient. Would definitely recommend them to friends and family.

    thumb Melanie Gross

    review rating 5  All I can say is Wow! Julian's crew arrived right on time - on the hottest, most humid day of the year - and installed my new old door. The guys were amazing - very professional, polite and clean. Their attention to detail was impressive and I couldn't be more pleased. Would wholeheartedly recommend, and definitely use them again!

    thumb Zooka
  • review rating 5  High quality windows, doing a great job to keep the cold out. They operate quite smoothly and pop out easy to clean them. Windows installed in one day. The installers were very courteous and friendly. Respectful of our home and ensured everything was cleaned and back together after the job was done. Very happy with the windows and work done, will be recommending Comfort Windows & Doors to friends.

    review rating 5  Julian did a great job! Excellent service, great price. Highly recommend Comfort Windows.

    thumb Adir Lobart
  • review rating 5  What a great experience dealing with Comfort Windows & Doors ! Right from the get go; working with Jules to decide on the perfect product choices up to the final installation. Couldn’t be happier with the process as well as the result! The installers were professional and courteous (left the space so clean you wouldn’t know they had worked there!) We replaced double front doors and given the quality of the Comfort Windows & Doors we regret we didn’t do so earlier. We will highly recommend this company to family and friends.

    thumb Shaylee Kianna

    thumb Tammy Cho

    review rating 5  We can't say enough about how wonderful the experience with Julian and his team was from beginning to end. Communication was so clear about our options. We never felt pressure.
